Interambulacral zones broad and composed of a large number of small, scale-like plates probably rather irregularly arranged. Individual plates with central primary tubercle that is perforate and non-crenulate; a few smaller secondary tubercles or granules around plate margin.

Peristome small; plating entirely ambulacral.

Lantern well developed with large grooved teeth composed of a biseries of elements in a V-shape.

Distinguished from Palaeodiscus by its quadriserial ambulacral plating. Close to Rhenechinus from which it differs only in having slighly more regularly polygonal interambulacral plates and smaller less obvious tuberculation. Gotlandechinus differs in having a uniserial arrangement of pore-pairs close to the perradius
